Before proceeding with a detailed description of the invention, since the invention is capable of other embodiments and of being carried out in various other ways, reference should be made to the following general description and the parts shown in the accompanying drawings. It is important to understand that the invention is not limited only to structure and arrangement.

It should also be understood that the terms used are for descriptive purposes and are not intended to be limiting.

The attached drawings show a marine propulsion system in the form of an outboard motor 11, which comprises a stern bracket 13 connecting the outboard motor 11 to the hull, and a stern bracket 13 that connects the outboard motor 11 to the hull, and a tilt bin 17 relative to the bracket 13. a swivel racket 15 connected to the bracket 13 for rocking movement perpendicular to the swivel bracket 15 and a swivel bracket 15 connected to the bracket 13 for pivoting movement perpendicular to the swivel bracket 15;
5, and the propulsion unit has an axis perpendicular to the bin 1T, that is, a kingpin 2
1 relative to the bracket 15 for a steering movement and relative to the bracket 13 for a pivoting movement together with the bracket 15 in the vertical direction.

The propulsion unit 19 supports a propeller 23 that is submerged in water under normal conditions.

Although the propulsion system is shown as an outboard motor, the invention is equally applicable to stern drives.

Ru.

According to the invention, the mounting is provided with a device or device indicating the vertical angle of the propulsion unit 19 or the swivel bracket 15 relative to the hull.

Further in accordance with the invention, the display device includes a gauge 25 including an indicator or pointer 27 movable in response to variations in current.
and a power source and device for varying the current supplied to the instrument 25 in response to vertical rocking motion of the propulsion unit 19.

Various instruments can be used.

The power source is preferably one that supplies direct current with a substantially uniform potential.

Therefore, in the structure shown in FIG. 2, the DC battery 31 is electrically connected to the meter 25.

The device for varying the current supplied to meter 25 in response to vertical rocking motion of propulsion unit 19 can be of various types and include a variable resistor 32 connected in series with battery 31 to connect meter 25 to battery 31. There is.

The variable resistor 32 includes a resistive coil 33 and a wiper 35 movably electrically connected to the coil for varying the effective resistance of the coil 33 according to the position of the propulsion unit 19.

Different coils and wipers can be arranged in different ways to vary the resistance of the coils according to the position of the propulsion unit 19.

In the structure shown in FIG. 2, the variable resistor 32 can be of various types and combinations.

It is combined with a cylinder-piston device 41.

More specifically, the hydraulic cylinder piston device 41
is a first member or cylinder 4 pivotally connected to one of the stern support plate 13 and the flexible bracket 15;
3 and a second member or piston assembly 45, which includes a piston rod 49 and a piston 47 pivotally connected to the other of the stern bracket 13 and the swivel bracket 15.

A piston assembly 45 is housed within the cylinder 43 and is movably housed therein relative to the cylinder 43 following vertical rocking movement of the propulsion unit 19.

In the structure shown in FIG. 2, the piston 47 is connected to the sleeve 5.
1 extends, and this sleeve supports a resistance coil 33.

This coil is wound around an insulating bobbin 53 and held in a fixed position relative to the piston 47 by a snap ring 55.

The wiper 35 is in the shape of a spherical contact that is held in electrical engagement with the coil 33 by a holding member 59 attached to the cylinder 43, and the holding body 59 is held by a holding member 61 made of an insulating material. Fixed.

As shown, retainer 59 houses a spring 65 that biases globe contact or wiper 35 into engagement with coil 33 .

Therefore, as piston 47 moves within cylinder 43, it changes the effective resistance of coil 33.

Coil 33 is grounded at one end, so that it is electrically connected in series with battery 31 along with meter 25.

As shown in FIG. 2, in this illustrated configuration, the end of the coil 33 adjacent the piston 47 is connected to the sleeve 51.
The other end of the sleeve is fixed to a guide 67 having an annular groove 69.

As shown in FIG. 3, a slider or contact 71 is positioned within the groove 69 which connects the end of the coil 33 adjacent the piston 47 to the sleeve 51 which is electrically connected thereto. ．． The guide 67 is electrically connected via the slider to the cylinder 43 and thereby to the outboard motor 11 which also serves as a ground for the battery 31.

Assuming that the piston rod 49 is fixedly connected to the piston 47, the effective resistance value will change in proportion to the amount of expansion and contraction of the hydraulic cylinder 41 due to movement throughout the permissible vertical swing range of the propulsion unit. it is obvious.

However, in the illustrated embodiment, the piston rod 49
7 and the piston 47 is movable only in a trim range of the permissible oscillating movement of the propulsion unit.

(Here, the trim range refers to the range in which the propulsion device is tilted in order to optimize the tilt of the propeller of the marine propulsion device depending on the inclination of the hull in the slipway and the state of waves on the water surface.

) Thus, in the configuration shown in FIG. 2, the instrument 25 will only indicate the angular position of the propulsion unit 190 relative to the equipment or hull during the trim range.

Hydraulic fluid within hydraulic cylinder arrangement 41 is retained only on the bottom side of piston 47 within cylinder ladder 43, with coil 33 and globe contact or wiper 35 positioned in a non-hydraulic fluid environment.

The meter 25, the variable resistor 32, and the battery 31 can be arbitrarily connected in series.

The circuit shown in FIG. 2 also includes a series connected key operated ignition switch 73 which is closed when the associated engine is running and open when the engine is not running.

An alternative arrangement or structure for creating a variable resistance or device that is variable according to the position of the propulsion unit 19 is shown in Figure I.

More specifically, in the structure shown in FIG. A rack 8 is provided.

Therefore, the rack 81 pivots together with the swivel bracket 15 and propulsion unit 19.

The stern bracket 13 is provided with a fixed variable resistance coil 33A housed within a bracket 83 which is suitably attached to a tilting pin 17 fixedly positioned relative to the stern bracket 13 or Can be mounted directly to the bracket.

Resistance coil 33A is electrically connected to wiper 35A, which is supported by bracket 83 for rotation about the tilt axis and is connected to pinion 85 which engages rank 81.

The mounting therefore changes the resistance of the coil 33A as the swivel bracket 15 and the propulsion unit 19 connected thereto vertically swing relative to the device or stern bracket 13.

The wiper 35A and the coil 33A are connected in series to the battery 33 and the wiper 35, similar to the connection between the coil 33 and the wiper 35 shown in FIG.
The current supplied to coil 33A changes according to the resistance value of coil 33A.

Furthermore, according to the present invention, the wiper 35A and the pinion 85
A friction slip clutch 87 is provided between the wiper 35A and the wiper 35A, so that when the propulsion unit 19 is initially fully moved to its fully raised or lowered position, the wiper 35A
is automatically positioned at an appropriate angle relative to pinion 85.

In this regard, the warper 35A has a propulsion unit 19.
There is a combination of one or more stops (not shown) positioned to prevent movement of wiper 35A beyond positions corresponding to fully raised or lowered positions.

Therefore, regardless of the relative angular relationship between pinion 85 and wiper 35, when propulsion unit 19 is caused to move vertically from its fully raised position to its fully retracted position, wiper 35A will move beyond the stop. Once engaged, the pinion 85 slides forward until the propulsion unit 19 reaches a fully raised or fully retracted position.

Next, when the pinion 85 moves, the wiper 35A moves in accordance with the position of the propulsion unit 19.
